my mother is almost 90 yrs old with cholestectomy 10 yrs ago. on October 9 she went into Ecoli septic shock due to 17mm stone in common bile duct(went very fast within 24 hrs). during the procedure she went into atrial fibrillation requiring cardioversion and digoxin overload so they just put the stunt and advise to do the procedure 2 months later. Now my mother is doing well, she does not have any Cardiac related issues, she is not on digoxin and almost on her baseling Question is is there a plastic or any other material stunt available that we can leave it without have to break the stone. Need advise
